Introduction to Excel Fractions
A fraction represents a part of a whole, such as 1/2, 3/4, or 5/8. Fractions are useful for measurements, recipes, construction calculations, and financial data.
Excel can work with fractions just like regular numbers. Although Excel stores fractions as decimal values in the background, it can display them in a fraction format for easier reading.

Format Cells as Fractions
Sometimes, Excel may interpret fractions as dates. To avoid this, I format these cells as fractions.
STEP 1: Select the cells containing the fractions.
STEP 2: Right-click and choose Format Cells from the context menu.
STEP 3: In the Format Cells dialog box, select Fraction from the list of categories. Choose a fraction type, such as “up to three digits”.

Use a Formula to Add Fractions
STEP 1: In cell C2, I type the formula:
=A2 + B2
STEP 2: Press Enter, and Excel automatically calculates the sum of 1/4 and 2/3.
Display the Result as a Fraction
By default, Excel might display the result as a decimal. For example, adding 1/4 and 2/3 gives 0.91666. To display the result as a fraction, I:
STEP 1: Select cell C2.
STEP 2: Right-click and choose Format Cells.
STEP 3: Select Fraction from the categories. Choose the appropriate fraction type (e.g., up to three digits).
Now the result appears as 11/12, which is the correct sum of 1/4 and 2/3.
